I took a long break from this sites (and similar ones), so I'm hoping this is the site I read this story on.
Description:
A high schooler is contacted on her phone from a man that found her number in a gas station bathroom stall or something. They talk, she meets up with him, there's other men there including one black male from school she recognizes, they live stream their activities etc.
I've tried searching but I can't find anything.
For a Good Time Call Kayla
by Vulgus
Synopsis: A naïve fourteen year old girl receives a phone call one evening from a man who claims to have found her name and number and an obscene offer for sex on a men's room wall. At first she's shocked and offended. But in a surprisingly short time she's talked into doing some previously unimaginable things.

No, it is there but your access is filtered (which is the default setting here, I think). I can't remember how to remove that filter but if you go to "My Account" you should be able to find it.
